T 0 all whom 2'25 may concern:

Be it known that I, CLAUs O. BRANDELL, a

citizen of the United States, and a resident of South Bend, in the county of St. Joseph and State of Indiana, have invented a new and Improved Device for Forming and Baking Food Products, of which the following is a specification. 1

This invention relates to means for forming and baking stems, pencils, or rods of dough and then breaking them nto short lengths, and its object is to prov de a food producing devicewhich shall he simple and eifective, which shall require llttle care, and which shall have a large output;

This invention consists of a plurality of cylinders for properly prepared dough and having small holes in one end, a piston for each cylinder and means to operate the piston to force the dough out of these holes, together with a movable carrier and an oven in which the carrier is mounted.

This invention also consists in building the carrier in the form of a drum formed of narrow transverse plates having sharp outer edges on which the stems, pencils or rods of dough will lie and beindented, so that after being baked they will break readily into proper lengths. This invention further consists in the various details of construction illustrated in the accompanying drawings and partlcularly pointed outin the claims I In the accompanying drawings Figure l is a right side elevation of the complete machine. Fig. 2 is a plan of the cyl nders and of the driving mechanism. Fig. 3 is a section on the line 33 of Fig. 1. Fig. i is an end elevation of themachine. Fig. 5 is a left side elevation of the front part of the machine. F 6 is a longitudinal section of the oven. Fig. 7 is a transverse section of the oven, on the line 77 of Fig. 1. Fig. 8 1s a rear elevation of a cylinder. Fig. 9 1s a section on the line 99 of Fig. 8. Fig. 10 is a section on the line l0'l0 of Fig. 6.

Similar reference characters refer to like parts throughout the several views. In the present machine, dough is placed in cylinders having perforated ends. Pistons are pressed into these cylinders so that the dough will be forced out of the perforations in the form of stems, rods or pencils. A movable carrier receives these pencils of soft dough and'supports them While they pass through a zone of sufficient heat to bake the Specification of Letters Fatent.

dong-Rafter which the pencils are broken up into short lengths orkernelsf The mechanism therefore consists-of two vice for forming, supporting and breaking up the pencilso .dough, and an oven.

The ongitudinal sills steel beams and support the frames and pedestals for the operating mechanism and the oven. At the frontendiof one sill may be mounted e f-motor 2 having a pulley-3 that connects to the pulley a on the main shaft 5 l by means of a belt 6 although any other desired means may beemployed to drive this shaft. Legs 6, 7,28 and 9 support the longitudinal bars 11, 12, 13 and 14, and the crossbars l5, l6, l7 and 18. The shaft 5 is mounted in a bearing 19 on the longitudinal bar 14: and in the bearing 20 at the "upper end of the pedestal 21. See Fig. 3. I

The shaft 5 has feathers or splines 23 and parts, a 'de'- '1 are preferably 24, over which the friction wheels 25 and 26 are slidahle, and by which they are driven. The friction wheel 26 engages the disk 27 on the shaft 28, as shown in Fig. 1, which shaft is mounted in the bearing 29 at the upper end of the pedestal 30, and bearings 31 projecting w fromthe oven. See F ig. 1. On the shaft 28 is a worm 33 which meshes with a Worm gear 3% on the shaft 35, which shaft is journaled in a bearing 36 -just within the oven, and also has a pinion 37 at its inner end. See Fig. 3.

The friction wheel 25 engages the disk 38 secured on the shaft 39, which shaft is .mounted in hearings on the cross-bars 16 and 17 and aiso carries the pulley 4O andbevel pinion 41, the latter secured to the shaft. This shaft also has a feather or spline 43 on which the clutch-cone 44 is slidable into and out of the tapering-chamber of the pulley 4.0. A ring .45 on the hub of the cone is engaged by the lever 46 on the shaft 47. Y

n the longitudinal Extending across betwee members 11 and 13 are the saddle bar 49 which support the cylinders 50, See Fig.5. Tn Figs. 8 and 9 these cylinders are shown to have ends 52 provided with perforations 53, and flanges 54 to extend down over the, rear face of the angle-bar as. A pivoted bar 55'is adapted to swing to vertical position'overtheirings 56 at the open ends of these cylinders. See Figs. 1 and 5.

Mounted on the cross-bars 15 and 48 are the bearings 57 for the stationary guide bars 58 and the bearing 59 for the screw 62. The rear end of the screw may be journaled in the saddle bar 49. The guide bars 58 carrv theangle-bar 48 and the shoes 59', best seen in Figs. 1 and 2, to which is secured the cross-head 60. This cross-head carries the ends of the piston rods 61 and the nut 63 for the screw 62. The screw has a worm wheel 64 on its front end and a pulley 65 to receive the belt 66 that also runs on the pulley l0 on the shaft 39. The worm wheel turns the screw to force the piston rods 61 into the cylinders and the pulley turns the screw in the opposite direction to withdraw the piston rods.

While the pistons may be of any desired construction, that shown in Fig. 5 is preferred, consisting of a piston 68, a dish 69 and a washer 70.

As stated'before, the wormovheel 6% turns the screw 62 to force the pistons into the cylinders, and the pulley 65 turns the screw in the opposite direction. The mechanism connecting the worm-wheel and pulley to the shaft 39 and for controlling these operations is as follows. Pivotally mounted on the front end of the shaft 39, as shown in Fig. 4c, is a yoke 72, which has a bearing 73 for the shaft 7 1. On this shaft are secured the bevel gear 75 and the worm 76, while a yoke 77 is mounted on the shaft and positioned by the worm which is adapted to mesh with the worm-wheel 6% on the screw 62.

Mounted on the upright 8 is a curved guide 7 8 which has a notch to receive the finger 7 9 that may hold the yoke 77 and the shaft 741 in such position that the worm 7 6 engages the wheel 64, during which time the pistons 68 will be moved toward the heads 52 of the cylinders 50. When the end of their stroke is reached, one of the slip pers 59 (Fig. 5) will engage an arm 80 on the slidable rod 81, and move it toward the rear against the tension of the spring 83. The finger 79 is on the front end of the rod 81, and the rearward movement of the linger releases the shaft 71, permitting it to swing to the left (in Fig. 4e) and the worm 76 to disengage the worm-wheel 6 1. This immediately stops the screw.

On the yoke 72 is a pin and a link 86 extends from this pin to the end of the lever 87 (Fig. 5) mounted on the shaft 4-7 that carries the lever 46. Therefore, when the shaft 7 1 swings over laterally and disengages the worm 76 and the wheel 64, it swings down the lever 87 and forces the clutch-cone it into the pulley 10, causing it to revo ve with the shaft 39, and thereby drive the pulley 65 on the screw 62 by means of the belt 66. This turns back the screw and moves the cross-head 60, the slippers 59 and the pistons forward.

When the forward limit of the movement of the cross-head 60 is reached, it will engage the arm 68 of a bell-crank lever mounted on the pin 89 carried by the side bar 13. The other arm 00 of this bell-crank connects to the lever 87 by means of a link misses 02. Swinging back the arm 68 will swing up the arm 87 and disengage the clutchcone 4% from the pulley 4:0 and thus stop the screw. This will be at a time when the pressure of the cross-head against this arm 88 is sufficient to support the shaft 74::- When this occurs, the cylinders 50 are removed and refilled, but preferably other cylinders, already filled, are substituted. The dough which is especially prepared for the purpose issues from the holes 53 under pressure of the pistons in the form of pencils or rods, all parallel to each other, and are received by a proper movable carrier within the oven and are there baked. The speed of the pistons and of the carrier may be regulated by moving the friction wheels 25 and 26 across their respective disks 38 and 27 by means of the arms 93 and 9t which are connected to the transversely slidable rods 95 and 96, to which the operating handles 97 and 98 are connected. A handle 99 may be mounted on the wheel 61 in order to adjust the pistons before the worm 76 is swung against the wheel 61.

The oven shown in the drawings is shown with sides 100 and 101, top 102, back 103, and the upper part 101 and the lower part 105 of the front, all preferably constructed of two sheets of metal with some good insulator between them. Burner pipes for gas 106 extend across through the oven and may be supplied by the feed pipes 107 and controlled by the valves 108. Doors 109 permit inspection of the interior. A small stack 110 with a damper 111 permits the escape of burnt gases.

7 The carrier for the pencils of dough may be of any desired construction, but is preferably in the form of a drum composed of two rings 112 and 113, the latter supplied with a ring of teeth 1141 which mesh with the pinion 37 on the shaft 35, whereby the carrier is revolved. Between the two rings the blades 115 are held by means of the bolts 116. The rings 112 and 113 rest on rolls 117, mounted in pairs on the shafts 118, which are mounted in bearings 119 on the outside of the oven, shown in Fig. 1. The pencils 120 of the dough are ejected from the passages 53 in an upward direction onto the carrier, where these pencils will rest on the sharp outer edges of these blades 115 and be indented thereby, so that after they are baked, they will readily break at these points. The space where these penoils of dough enter the oven may be nearly closed by means of a door 122, mounted ona shaft 123 and operable by the handles 1241.

A small shaft 125 extends across the oven, as shown in Figs. 6 and 7, and has a pinion 126 secured to it which meshes with the ring of teeth 114 of the dough carrier. 0n the shaft are mounted the collars 127 which are slotted radially and longitudinally to hold the narrow'blades 128'which form a breaking roll of such diameter that the blades 128 will just enter the spaces between the blades ,115 and therefore break the-pencils of dough resting on the carrier, both at the blades 115 and between them, so that these pieces will fall into a trough 129 in the rear of the oven.

Inthe trough 129 is a screw conveyer 130 on the shaft 132, mounted in bearings 133 and carrying a sprocket wheel 13% shown in section in Fig. 7 and indicated in dotted lines in Fig. 6. A driving chain 135 may connect this wheel to a similar wheel 136 on the rear shaft 118. The spout 1 10 extends through the side of the oven from the trough. Guide plates 1&1 on the guard plate 142 prevent the pencils of dough from swinging out of place on the carrier just before being broken up.

While the preferred form of dough carrier, pencil forming means, oven, and driving mechanismhave been shown, the skilled designer is not restricted to their details but may change them as may be found necessary and desirable without departing from the spirit of my invention as setforth in the claims.
